(c) an automatic firearm, whether or not it has been altered to discharge only one projectile with one pressure of the trigger

That is the prohibition that applies to CAs.

I'm presuming that the specimen submitted had been scratch manufactured as semi. If it was a remanufactured FA gun, then the classifiaction is correct under the law.

The VZ58 type rifles come to mind: they were manufactured using brand new, never assembled, selective fire receivers, altered to semi prior to being used in a rifle. This concept was specifically approved by the RCMP.

The design of a semi-auto version was derived from full-auto machine-pistol. Even though it has similar in appearance and dimensions full-auto version, it has scratch manufactured receiver, was never assembled as full-auto and then converted to semi-auto.
As I said before the semi-auto receiver is not the same as full-auto receiver, and trigger group and bolt assembly are different as well. The semi-auto receiver won't accept full-auto parts from its cousin....
